IMPROVEMENT lIN WATER-CLOSET. VALVES.

Specification formi-ng part of Letters Patent No. 158,646, dated January 12, 1875; application tiled August 17, 1874.

To all 'a0/tom tt may concern:

Be it known that I, EDWIN MILLS, ofSomy erville, in the countyof Middlesex and Colnm'onwealth of Massachusetts, have invented a lnew and useful Improvement in Valves for Water-Closets, of which lthe following, taken in connection with the annexed drawings, is

a full, clear, and exact description.

Water for clearing the bowl in a waterclosetis usual-l y drawn from an elevated tank.

In 0r under the bottom of the main tank there is placed a small supplementary tank or ves- Vsel calculated to contain water enough to wash out the bowl below. Upon raising' the valve cover or stopper, marked in the drawing D, water ilows from the main tank through the "valve into the supplementary tank or vessel upon which the valve is placed, and the pipe conducting it to the bowl..A rlhe handle being released," the valve cover or stopper D closes,

' and unless air is admitted to the4 supplementary tankv or'vessel below the valve cover or stopper l), the water in the supplementary tank is suspended and cannot flow through the conductingpipe to the bowl below.

Heretofore, the admission of air to the supplementary tank or vessel, so that the water in it might ilow to the bowl, has been effected by `soldering a pipe into it to extend above the water-level in the main tank. The supplementary tank being generally placed below the bottom of the main tank, to enable it to ,take water as lorg as any remained in the main tank,theairpipe had not only to be-sol- -dered into the supplementary pipe, but also carried through and soldered into the bottom scribed.

of the main tank, which is a difficult job to make securely tight, and therefore quite costly Lvhen the work is made perfect as it ought to The object of the invention is to provide a more convenient and cheap method of connecting the air-pipe with the supplementary tank or vessel in or below the bottom of the main tank.

In the drawing, of the valve; on one side ot' A. C is .a col-lar screwed to A is the cylinder or body the bottor'n vof A to connect the valve to the supplementary tank or vessel under it. D is the valve cover or stopper, Weighted in the usual manner, and E is the g'uide rod or stem ofthe valve cover or stopper.v The hollow boss B'has a teat with an opening upward, into which the air-pipeds inserted either with a scrcwor ground joint, or by soldering. lA

piece of brass or other rigid metal pipe, ground in to make a tight lit, so that it may be lifted out and replaced at pleasure,`is mostdesirable.

This pipe, when earriedjust above the surface of the water in the main tank, may also serve as an overflow or waste-water pipe.

I claim as new- In a watercloset valve, the hollow boss or projection B, with the tea-t opening, upward to receive the ai r-pipe, .substantially as de- EDWIN MILLS.
